Hi All:
Sorry that this isn't really an EPICS question, other than the tenuous
connection via Alarm Handler.
The question has been raised here about how to ensure that the audible
alarms from Alarm Handler are always audible. A number of places exist
where this can be disabled. The speakers can become faulty, the
wall-wart commonly used to power the speakers can become disconnected or
faulty, the volume control on the speakers can be turned down, the host
OS software controls can be turned down or muted either through accident
or software fault, audio cables can become faulty, and sound card
hardware can become faulty. Most of these will manifest only in silence.
Has anyone undertaken measures to monitor any of these components in
some way, or implemented hardware which is not subject to the common
frailties of commodity audio equipment used for control room alarms?
Any suggestions cheerfully accepted. Thanks.
